Main figures, all systems together
Figure 4.
PFAS predictions in all systems together. (A) The PFAS in each diet item were known and provided during the modelling. (B) The PFAS values were estimated based on the food web trophic interactions, the only known PFAS values here were in water and sediment. The dot models values when fish tissue PFAS, water, and sediment values are at their measured mean values. The food web structure was the same between both cases. The dotted lines mark log values of 2 and 10 showing where values are over- or under-predicted by a factor or 2 and 10 respectively.
Figure 5.
Model bias in each system by PFAS. The perfect fit is at MB = 1. When values reach 2 and 0.5, they are systematically over-predicted or under-predicted by a factor of two, respectively.

Model bias in each system by species. The perfect fit is at MB = 1. When values reach 2 and 0.5, they are systematically over-predicted or under-predicted by a factor of two, respectively.
